Preimplantation Genetic Diagnosis (PGD) is a laboratory procedure that provides genetic information about embryos prior to their transfer, or implantation, into the uterus. The information obtained through PGD is used to select the best embryos for transfer.
How PGD Works
A single cell is removed from an eight-cell embryo and is used for diagnosis. The procedure requires considerable skill and does not affect the embryo’s viability.
At New England Fertility, we use a sophisticated laser to create an opening in the zona pellucid (or strong membrane that forms around an ovum as it develops in the ovary), which then allows the cell to be extracted.
What PGD Can Detect
Aneuploidy (An Abnormal Number of Chromosomes)
Any deviation from the normal number of chromosomes (extra or missing chromosomes) can lead to miscarriages or birth defects (such as Down syndrome). Counting the chromosomes and ensuring a correct number allows New England Fertility to pick the best embryos for transfer.
Single Gene Defects
A variety of conditions (cystic fibrosis, muscular dystrophy, sickle cell anemia) are a result of a defect in a single gene. By using PGD, New England Fertility can check for defective genes and identify and isolate unaffected embryos.
